Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2013-04-25
Assessor(s): Akhani, H., Zehzad, B. & Brummitt, N.
Reviewer(s): Lansdown, R.V.

Justification:
Although there is habitat degradation across the range of Equisetum telmateia, this is not currently affecting the status of this species or threatening its survival; it does not meet any of the IUCN criteria for threatened or Near Threatened status and hence Least Concern is the most appropriate category for this species.

Habitat and Ecology [top]

Habitat and Ecology:Equisetum telmateia is a deciduous herb found in open habitats, eroding sea and river cliffs, roadsides and railway embankments growing in base rich clay soils on sites with permanent seepage and on porous clay rocks (Online Atlas of the British and Irish Flora 2012). In Northern Iran it occurs along shallow rivers in forest zones, forest margins, degraded forests along streams and water runners, road sides, at the margin of wetlands, and sometimes as a weedy plant in wastelands and on the margins of paddy fields.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: A plant used in traditional medicine for its anti-inflammatory and diuretic properties and antioxidant activity of aqueous extract (infusion) or as a decoction to stop excess urinating. A poultice of the rough leaves and stems is applied to cuts and sores (Correia et al. 2005, Plants for a Future 2012). It is also used for its antibacterial properties to treat infections. In Turkey, at least, it is one of the most commonly used plants (Uzun et al. 2004). The root and fertile shoots can be eaten cooked and the stems are used for making floor polish. In Iran used as a medicinal plant in traditional medicine for a variety of purposes including kidney stones and against cancer, blood coagulation and bladder tension (Ghorbanalizadeh 2011).

Threats [top]

Major Threat(s):

There is evidence of localized habitat degradation in some areas where this species occurs, however, this is not thought to be severe enough to pose a threat to the species currently or in the near future. The species appears to be tolerant of some disturbance as it grows in wastelands and agricultural areas like paddy fields.

Conservation Actions [top]

Conservation Actions: It is described as rare in the Czech Republic (Holub and Procházka 2000) and is listed as Critically Endangered in the national red lists of Belarus (Ermakova 2005) and Sweden (Gärdenfors 2010). However, it is classed as Least Concern in a number of countries including Denmark (NERI 2007), Germany (Ludwig and Schnittler 1996), Luxembourg (Colling 2005), Switzerland (Moser et al. 2002) and the United Kingdom (Cheffings and Farrell 2005).

In Sweden, conservation efforts have been made but it is argued that gradual population declines will eventually lead to its unavoidable extinction which may be characteristic for populations of long-lived perennials on drained or otherwise damaged sites. In such situations, it may be questioned whether conservation efforts, known to only postpone the extinction, are worthwhile (Mattiasson 2000).

The few known localities of this plant outside of the forest zone of the East Mediterranean requires conservation specially against converting of its habitat for agricultural purposes.
